Question
A solenoidal coil with 24 turns of wire is wound tightly around another coil with 350 turns. The inner solenoid is 25.0long and has a diameter of 2.50. At an assured time, the current in the inner solenoid is 0.110 and is increasing at a rate of 1500.
For this time, compute average magnetic flux through each turn of the inner solenoid?
For this time, compute mutual inductance of the two solenoids?
For this time, compute emf induced in the outer solenoid by the changing current in the inner solenoid.
